Love the look but runs narrow
Size: 7 Toddler, Color: Navy, Size: 7 Toddler, Color: Navy
Obsessed with the navy, it literally goes with everything. Quality is great too, really happy with how they’re made. Super cute too.
Only thing is my son has wide feet and they ran a little tight on him. If your toddler is on the wider side, might be worth sizing up.
Overall still happy with them!

Snug fit with ease of putting on
Size: 7 Toddler, Color: Navy, Size: 7 Toddler, Color: Navy
These Amazon Essentials hook-and-loop athletic sneakers have been a fantastic everyday shoe for toddlers and little kids. The fit and comfort really stand out. The padded collar and cushioned insole make them comfortable enough for all-day wear, whether that’s running around at school, playing at the park, or just being on the move at home.
One of the biggest wins is how easy they are for kids to put on themselves. The hook-and-loop closure combined with the faux elastic laces strikes a great balance between a secure fit and independence, which is a huge plus for busy mornings. They stay snug without being tight and don’t slip off during active play.
The materials feel well made for a kid’s sneaker. The faux leather and mesh upper looks sporty and holds up well to daily wear, while the mesh lining helps with breathability. The TPR sole provides good traction and stability, giving a solid, supportive feel without being stiff or heavy.
Style-wise, these shoes are versatile and cute. The athletic look with subtle vintage-inspired details works with everything from play clothes to more put-together casual outfits. Overall, these sneakers deliver comfort, durability, and kid-friendly design at a great value. A reliable, no-fuss choice for active little feet.

Slim toes and runs small.
Size: 11 Little Kid, Color: Metallic Gold
These sneakers ran small and are very slim down the foot. Definintely not wide friendly or even toe box friendly for those who want more friendly 'barefoot' shoes. The colors are cute. Easy to put on and off, especially for toddlers with the lack of laces. Just not a great sneaker for those who want something that will last longer and not pinch toes or create ingrowns.
